Ravenheat HE85 T faulty

[spazgow]

hi everyone,
Ive just been to a ravenheat he 85t combi boiler and the heating and hot water are not working. Ive check that there is power, gas supply and made sure that the pump is working and my first thought was the fan. So followng the fault finding in the brochure and even enquiring with Ravenheat who also said it was the fan. So ive changed the fan and I still have the same problem! (no heating or hot water). dose anyone have any idea what it could be??

A multi meter will be your new best friend, you cant really fault find without one.

I have the same boiler and when i fire up the CH from the room stat it fires up for about 2 secs then goes off then comes on and goes off? When i run the DHW and then turn the tap off the CH stays on?
What is the problem as the 2 engineers who have been out both fitted a new thermistor but nothing happened?
